OUD-BURNER TORCH.

Application led May 14,

To all whom t may concern:

Be it known that I, FREDERICK WILLIAM KELLERMANN, a citizen of Germany, and a resident of the city of New York, Port Richmond, borough of Richmond, in the county of Richmond and State of New York, have invented a new and Improved Oil-Burner Torch, of which the following is a full, clear, and exact description.

This invention relates to burners for use on mechanics torches or analogous purposes, the structure being such as to adapt it to the use of liquid fuel combined with air or the like.

Among the objects of the invention is to construct a torch of the nature set forth, whereby the greatest efficiency of heat is obtained in connection either with a hand torch or for use in connection with a power operated apparatus.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specilication in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a vertical longitudinal section of a burner made in accordance with this invention, the section being on the line 1-1 of Fig. 3; Fig. 2 is a horizontal sectional detail on the line 2-2 of Fig. 1; and Figs. 3 and 4 are vertical transverse sectional views on the corresponding lines of Fig. 1;

r1`he several parts of this device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fullv described and claimed.

Referring more particularly to the drawn ings, I show at 10 a tubular casing of any suitable form in cross section but indicated as cylindrical, surrounding the ends of which are collars 11 and 12, the collars being rigidly secured to the casing and provided with outwardly projecting flanges through which a plurality of rods 13 extend, the rods being secured in position by nuts 141 on opposite sides of the flanges. As shown in r ig. 1, however, the flanges and collars may be broken away, forming in effect simply a series of ears for coperation with the rods.

15 indicates a disk secured in the rear ends of the rods 13 by nuts 16 and held spaced Specification of Letters Patent.

from the rear end of the casing 1() hy means of certain of the nuts 1&14 as shown in Fig. 1. The disk or head 15 has a central hole 17 through which the rear end of a peculiar form of nozzle 1S projects and is locked by means of a thimble 19 which provides an air chamber 20. The main portion of the nozzle lies centrally within the casing 10 and constitutes the main support for a peculiar arrangement or system of generator pipes 21, 22 and arranged within and spaced from the wall of the casing 10.

Liquid fuel is delivered from any suitable source and by any desired means centrally through the space 2O within a tube 24; into the central port 25 of' the nozzle which delivers it to a transverse vertical port 21 communicating with the generator pipes 21 at the top and bottom of the system. These pipes 21 at their front ends communicate with the annular pipe 23 which lies just within the outer or front end of the casing 10 and which serves to deliver the fuel in vaporized or Seini-vapoii'ized form rearwardly through the pipes 22 to the transverse horizontal port 22 into a central axial port or pocket 26 where the now fully vaporized fuel is delivered into and through a tip 27 having laterally directed delivery ports 27 which cause the vapor to strike against the outwardly flared wall 23 of' a recess formed in the outer or front end of the nozzle. The vapor from this pocket fills the inner concavity 29 of a cap 30 secured to the outer end of the nozzle and from which the vapor is j etted forwardly through a central hole 31 along the central axis of the nozzle and whence it is delivered in the form of an intense flame through and beyond a hood 32 comprising inner and outer shells 33 and 34 respectively, held in spaced relation to cach The outer ends of the shells are spaced by means of an annular spacer The rear ends of the shells 33 and 311 are secured to the outer end of the easing 10 by fasteners such as screws 3G but close together allowing the flame to pass outwardly through the holes 32 to keep the inner shell h ot.

The supply of liouid fuel through the tube 21 may be delivered from any suitable source (not shown) such, for instance, as a hand torch under the force of compressed air furnished by a hand pump attached thereto in accordance with the usual practice, or from a larger tank under the influence of pressure Cil ' turns through the tubes'22 and transverse ports 22 into and through the central chamber 26 to and through the tip 27. The tubes 2l, 22 and 23 being maintained hot by the flame shooting forwardly through the port 3l serve as generators of from the liquid fuel introduced from the tube 24.

In order to introduce a supply of air or vits equivalent through the nozzle into the mixingehamber 9.9, recourse is had to a pipe 37 controlled by a cock 38 and communicating With the thimble chamber 20 surrounding the tube :24. This chamber communicates With the mixing chamber through a plurality of ports 39 shown in Fig. l and indicated longitudinally by dotted lines in Fig. l, the delivery ends of the ports ilcommunicating directly With the flaring surface 2S surrounding the tip 27.

l claim:

l. ln a device of the nature set forth, the combination of a tubular casing, a heave secured adjacent one end of the casing and in spaced relation thereto, a nozzle fitted centrally in said head and lying mainly Within the casing, means to supply fluid fuel through the nozzle into the interior of the casing, and a generator of gas ivithiii the casing and comprising longitudinal tubes communicating with the nozzle to receive the fluid fuel therefrom, an annular tube receiving the fluid fuel from the tubes aforesaid, and other tubes leading from the annular tube back to the nozzle, substantially as and for the purposes set forth.

2. ln a device of the character set forth, the combination of ahead, a nozzle fitted therein, a casing surrounding and spaced from the nozzle, means to deliver fluid fuel into and through the nozzle, and a generator of gas secured to the nozzle Within the casing, said generator comprising a plurality of longitudinal tubes arranged Within and Y parallel to the casing with their rear ends securedto the nozzle and an annular tube connected to the front ends of the longitudinal pipes and providing communication between them.

3. The combination of a head, a nozzle having one end secured therein, the main portion of the nozzle lying on one side of the head, a thimble secured to the other end of the nozzle and serving to lock the same to the head, means to deliver liquid fuel into and through the nozzle, means to deliver air through the thimble and thence through the nozzle independently of the means for passing liquid fuel therethrough, and ar cap embracing the delivery end of the nozzle and providing therein a mixing chamber for the gas and air delivered thereto.

4l. rlhe combination of a nozzle having central axially aliued ports spaced from each other. each of said ports having laterally extending ports.y means to deliver fluid fuel into one end of the nozzle tl'irough one of the first mentioned ports. the fuel passing thence laterally through certain of the lateral ports, means to convey the fuel from the ports last mentioned to the outer ends of the other lateral ports whence it is returned to the nozzle and delivered through the alined port, a tip secured to the delivery end of the nozzle in alineinent with the last mentioned port, and means forming a mixing chamber surrounding the tip.

5. The combination of a nozzle, means to hold the nozzle in position, said nozzle being formed with a flaring cavity in its delivery end, a cap embracing said end forming with the cavity a mixing chamber, means to deliver air through the nozzle lengthwise into said chamber, means to deliver liquid fuel into the nozzle remote from the mixing chamber, and a generator of gas receiving the liquid fuel thus delivered and returning it for delivery into the mixing chamber.

6. The combination of a head, a. nozzle having its receiving end fitted in said head, a liquid fuel tube fitted in said receiving end of the nozzle, a thimble surroundingT the tube and spaced therefrom, said thimble serving to lock the nozzle in place in the head and providing an air chamber surrounding the tube, a tubular casino,- surrounding` the delivery end of the nozzle and locked to the head, generatino` means ivithin the casing and supported by the nozzle, means to deliver air from the air chamber to the nozzle and means for mixing the `ras and air Within the casing.
